Finite element simulation of the cold forging process having a floating die

In this paper, a finite element technique of analyzing a forging process having a floating die is presented and its numerical characteristics are investigated in detail. The rigid-plastic finite element method is employed together with a search scheme of obtaining the proper floating die velocity that makes the floating die load to be less than the user-specified tolerance. An application example of an axisymmetric three-stage cold forging process having a floating die is given.
